image2 plugin should have a way to allow for custom image tags that won't be upcast

[Matthew]

Steps to reproduce

I have a plugin that generates <img> placeholders and when image2 is installed it's causing a number of errors because upcastWidgetElement is attempting to convert it to a widget. There is already a special case in here to avoid the 'data-cke-realelement' but it would be nice if there was also a way to specify a editor.config property for additional class(es) (or attributes) that could be used to flag other <img> that we also didn't want to be processed by this method. This would avoid modification of this method.

I could possibly add the data-cke-realelement attribute to the img but that would still not fix any previous placed images.

Thanks!

Expected result

Only image tags not part of this list are upcast

Actual result

All image tags are upcast

Looks like a duplicate of #11186.

It seems that point 3 mentioned in that ticket will solve your problem once this feature is implemented.

Sorry, I have missed that #11186 has already been implemented :P

Thanks for the reply, I didn't see that option, I'll try it out!
